1916.] NATURAL SCIENCES OF PHILADELPHIA. 89 



Smaller series have also been examined belonging to the North 

 Carolina Department of Agriculture, the Museum of the Brooklyn 

 Institute of Arts and Sciences, the Pennsylvania State Department 

 of Zoology and the Museum of Comparative Zoology. The neces- 

 sity of seeing the historic Scudder Collection in the latter institution, 

 to which three visits were made while preparing the present paper, 

 is always very pressing in work on the North American species of the 

 Orthoptera. 



In order to reduce the length of our entries and yet give complete 

 data, we have used in the present paper, as in a number of previous 

 ones, standard abbreviations for the sources of the material, or, in 

 the case of the larger series which can be located by the collector's 

 name we have considered the latter sufficient to place the specimens. 



No location is given for material collected by Rehn and Hebard, 

 jointly or individually, as it is understood it is in the Philadelphia 

 collections, either the Academy of Natural Sciences or the Hebard 

 Collection. Material in the collection of Mr. W. T. Davis, of New 

 Brighton, New York, collected by himself, and that of Dr. A. P. Morse, 

 of Wellesley, Massachusetts, collected by the same individual, has 

 no location given for it, as it is understood such material is in their 

 respective collections unless otherwise specified. Material collected 

 by other individuals in the Davis and Morse- Collections, has the 

 location indicated by the abbreviations given below. No location 

 is given for material credited as collected by Dr. J. Chester Bradley, 

 it being understood that is in the Georgia State Collection at Atlanta 

 unless from localities in the Okeefenokee Swamp, in which case it is 

 in the collection of Cornell University. From each of these col- 

 lections a representation has been retained in the Philadelphia 

 collections in return for the work of identification.

 present paper are as follows: 



A. N. S. P., for the Academy of Natural Sciences of Philadelphia. 



B. I., for the Museum of the Brooklyn Institute of Arts and Sciences.
